 Description   

From the attached screenshot:

a) The number of available bytes for reuse > 6GB

b) However the DB is constantly growing and the file size of this collection is constantly increasing.

This appears to be only an issue since moving over to 3.6.13. 

Any ideas why the existing space is not being used first?

Because we never received a response, closing this ticket as Incomplete. Please let us know if this is still a seeable problem.

Unfortunately, there are many reasons why allocated bytes would not be reused in an efficient manner and it can be very difficult to determine which is the particular reason here. Have you attempted to run compact or performed an initial sync on the nodes that you have noticed are not reusing space?
